Sodium intake of infants varies widely with the type of food consumed. However, few reports are available describing the nutrients, including sodium values, of dietary intakes of infants receiving supplemental foods. The purpose of this study was to determine the sodium, energy, and nutrient values of diets for infants from low-income families participating in the WIC program. The sample consisted of 306 infants, aged 4 through 7 months, who were seen in well-child clinics. Approximately 200 of the infants were reportedly fed commercially prepared baby food as the only solid food; 55 received 50% or more of their energy from table foods. The dietary intakes of infants receiving supplemental foods and consuming commercially prepared baby foods included significantly less sodium than the intakes of infants fed primarily table foods. As a group, all infants met the RDAs for most nutrients but had higher sodium values than reported by other researchers. The group of infants for whom consumption of table foods was reported had values above the acceptable range for sodium primarily because the caregivers failed to provide low-sodium, nutrient-dense, supplemental foods in the quantities prescribed but instead substituted sodium-dense meat and vegetable products.
